Question about data storage.

I have a question about data store when it comes to iOS applications. I have searched the documentation and couldn't find an answer.

Say I want to create a simple note taking application. I want to store the notes in either an array or a dictionary. When I append a new note to either an array or dictionary, does that append retain its value after I restart the application?

If it does not, how would you go about creating a file? Also, how would you read and write data to that file?

This is a pretty complicated question, so a link to a related discussion or document would be great. Also, I am looking for the Swift equivalent to this.

hi, if you can , i recommend to watch here . He tells you everything from beginning very detailed . Here on treehouse i think the introduction is a bit poor to C .

get to the storage article , here I'm on loops.

You could also achieve this with using core data in swift. Treehouse does not currently offer Core Data courses in Swift but I am sure it is in the works. They do offer a Courses on Core Data in Objective-C but if you would like to do this in swift I found this video that might be able to help you out. :)
